This week's Tech Tuesday takes a closer look at rebuilding the Motion Control damper of your RockShox fork. Inside you can watch a video straight from the smart minds at RockShox that details all of the steps needed to keep your fork running smooth and consistent.
Keeping your RockShox fork running smooth and consistent is easier than you may have imagined. All you need is some tools and oil, and after reading the instructions and watching the video below you'll be ready to dive into it. The question is though, how often should you do this job? RockShox recommends dropping the lowers off for cleaning and adding new lube oil ever 50 hours of riding, but as always, you should do it more often if you are riding in nasty conditions or you notice that your fork isn't as smooth as it should. The damper service covered here should be tackled after 100 hours of riding and it is good practice to replace any O-rings or wear items at this time as well. As with any repair job, if you don't feel comfortable tearing into your fork you probably shouldn't be doing it. Take it down the road to your local shop and have them perform the work instead. Motion Control dampers can be found on RockShox BoXXer, Pike, Reba, Recon, and Revelation forks.
Some pointers before you begin...
• Think you're tough? You won't be when you get fork oil in your eye. Wear some glasses and nitrile gloves to lesson the chance of having an incident. • There is a good chance that you're going to make a mess during this job, especially if it is your first go at it. Not only do I recommend wearing gloves and eye protection, but it also doesn't hurt to put down an old towel on the floor to soak up any spills. Be sure to properly dispose of your old oil as well, not by just pouring it down the drain! • You'll be dealing with some small parts during this job, including the foot nuts and the very small detent ball and spring tucked up in the high-speed compression knob. Don't lose them! Having a small dish or container to put these bits in after removal can save you from spending a lot of time on your hands and knees scouring the floor. • You'll have to remove your fork's lower legs before being able to service the Motion Control damper. Check out this video if you need some guidance on how to do this. Once you have the lowers off, take a few minutes to inspect your stanchion tubes to be sure that they don't have any fatal scratches or dings in their finish.
If you've never had your fork apart you'll be doing yourself a big favor by taking a few minutes to read the instructions found on the RockShox site before watching the video below. Better yet, print them out to have them on hand in case you get lost. You'll also find the correct oil weight and volume levels for each fork as well. This is very important - too much oil in the fork's damper will prevent it from attaining full travel and possibly damage the internals. Too little oil and your fork will suffer from inconsistent damping... get it right!
What's needed:hex key set, internal and external snap ring pliers, 24 mm socket wrench, a pick or awl, isopropyl alcohol, rag, 5 wt. suspension fluid, and an oil pan (an old Tupperware container works great)
